The reason why the oil level of special transformer is too high

Reasons for high oil level:

1. The change of the temperature of the special transformer can change the oil level. With the change of the oil temperature, the oil level will also appear correspondingly - a change of a certain scale. However, under abnormal circumstances, due to oil seepage, water seepage and other faults and other things will also cause abnormal changes in oil level;

2. The change of oil temperature is related to load conditions, ambient temperature and other conditions. When the oil level change is inconsistent with these factors, it may be a false oil level. The reasons for the false oil level: a. The oil standard pipe is blocked; b. Explosion-proof Pipe vents are blocked;

3. If the oil level is too high, an oil spill will be formed.

Treatment methods and emergency measures:

1. If there is gas relay protection, the trip circuit will be lifted to avoid false tripping;

2. The operator on duty should always check the oil level indicator, and if the oil level is too high, they can drain the oil in an appropriate amount;

3. When abnormal oil injection is found in the oil pillow or explosion-proof pipe, the power supply of the special transformer should be cut off in time to avoid failure and expansion of the incident.

If the oil level of the special transformer is too high, it is necessary to find a way to reduce it. If the oil level is too high, it will easily cause the equipment to overheat, which will affect its operation. If the situation is serious, it will likely burst. We must treat this work with caution. .
